' stoves, its object being to provide means for utilizing y coupling ring 15'* which is ilanged for a seamed conneca greater proportion of the generated heat and more effectually heating air and discharging the same for circulation in the room or apartment to be heated.

Another object is to provide a stove o this character which in*addition to possessing the foregoing advantages is simple of construction', easily regulated, ornamental in appearance, and susceptible of manufacture and sale ata low costi In the accompanying drawings,-Figure 1 is a view partly in elevation and partly in vertical section of av heating stove embodying my invention. Fig. 2 is a top plan viewthereoi. Fig. 3 is a horizontal section on vline z-fl; o Fig. l. Fig. 4 is a detail section on line y-y of Fig. 1-. i I In the drawings, 1 designates the base or ash pit and f2 the re box of the stove, which .may be oi any preferred construction and provided with doors in the usual way. The lining of the fire box vis formed at top with an inwardly exteiiding horizontal flange 3 which supports the drum or main heating chamber 4, the latter consisting of a shell of sheet metal or other suitable material having a top plate or head 5 provided with an opening of proper form toreceive and hold a closing lid i or plate 6: The flange 3 further protects the base of the main heating chamber from the direct action oi the radiated heat of the flre.

. Surrounding the inner drum or shell 4 and arranged concentric therewith are inner and outerA heating jackets 7 and 8, spaced to form intervening chambers 9 and 10.l The inner jacket 7 comprises a shell supportedat-v its lower end from the fire box by bracket pieces 11 and provided at its lower end with a short outwardly extending annular Iiange 12 and at its upper end with an inwardly extending flange 13. rlhe flange 12 forms a support for the outer jacket 8, which has an inwardly extending flange 14 resting thereon and riveted or otherwise secured thereto, the said flanges l2 and 14 forming a closure lor the lower end of the outer chamber 10. Thel upper end of the jacket 8 has a ange 15 coupled to the ange' 13 of the jacket 7 by a tion therewith and forms a closure for the upperV end of the chamber 10.:A A depending rim flange or skirting 16 may be provided at the top of the jacket Sto give an ornamental or nnished appearance to the upper portion of the stove body. Hand-holes 17 closed by air tight screw caps 18 are provided in the jacket 8 to enable the Specification of Letters Patent. l Application filed .Tune 28,1906. Serial No.. 323,760.

chambers 10 to be cleaned and to give accessto the heads and nuts of bolts, rivets or other fastenings used to `connect the anges 12 and 14 and to fasteny the brackets 1l. It will'thus be seen that the Aouter heatiing chamber 10 isiclosed at top and bottom, lwhile-the chamber 9 is open at its lower end for the entrance oi air and communicates at its .upper end with a crown drum or hood 19 suitably mounted upon the upper ends of the jackets. The hood 19 is formed. in its top with an opening with which communicates a rotary air discharge flue 20. This nue is preferably in form of a fold-` ing' or telescopic elbow, so that it may'be extended or contracted to discharge the heated air *vertically or horizontally. By turning the flue on its axisfsaidv lue may be disposed to discharge the heated air at any point in its plane of rotation, thus enabling the air to be circulated in` any preferred manner throughoutthe room or compartment.

The main drum 4 communicates with the outer charm. 'ber 10 through connecting flues 23, and a fuel door 24 is provided to give access to the base of the heating chaml ber 4 in the usual manner. The chamber 10 communicates at its lower end with the lower end oi an outlet iiue or pipe 25, and may also communicate at its upper end with said iue through a connection 26, in which yis arrangedan airl-tight direct-draftl damper271to control the discharge 'of the products of combustion therethrough. A -curved shield or skirt 28 depends from the lower edge of the outer jacket and covers the space below the same and between the two jackets and the upper edge of the re box, and forms an ornamental fixtigre to conceal the space as well asa delector to guide the air into the lower end'o the inner chamber 9.

The top plate or head 5 of the main drum 4is provided around the opening therein with a depressed seat recess or guideway 29 in which, at suitable intervals,

are formed apertures 30. An annular valve or damper plate 31 is seated in and turns within said recess and is provided with a corresponding series of apertures 32 adapted to register with said apertures 30. The valve or damper may be retained in position in any preferred manner and is provided with an operating lever or handle 33 extending through a slot in the front of the hoodl and limited in its reverse movements'by stops 34. By

vadjusting the valve or damper through this handle the sets of openingsvBO-and 32V maybe thrown into'and` out 'of registering relation to open or close communication between the main drum and hood.

The operation is as follower Thevalve or damper 31 normally closes theopenings 30, so that the heated air andproducts of, combustion pass from the main drum 4 through the outlet lues 23 into the outer' heating` chamber l0, and iinally discharge through the outlet flue 25, the rapidity of exhaust of said productsbeing controlled by regulating the damper 27. Air from the exterior enters the lower end of thechamber 9 and' iiows upwardly-therethroughand into the hood and finally discharges ina heated condition through the 'discharge fine 20 back into the room. In thus passing through the chamberB the air is heated by direct contact with the shells 4 and 7 and by the radiation of heat therethrough from the interior o f'the `main,` and outer chamber 10, so that in its passage through' the chamber 9 it will be heeredfto e leigh` degree.` By. ede justing the flue this heated air may be caused to discharge at any desired elevation and` toward any desired portion of the room or apartment.l When the damper 27 is closed, the products oicoxnbustion take the longer course and discharge, through the chimney ilue 25, entering the lower end 0f said 11u12` at the base of chamber 10. The draft may be increased to a maf terial degree by turning thevalvei'or `damper 31 until the perforations` 30 and 32 register, whereupon air from Athe head drum `19 will pass down through said perforations into the main heating chamber and-then flow with the productsoi combustion to vthe chimney fine 25.

It will be apparent that the construction described is not only productive oi ythe advantages before stated, but heats the circulating air to' a much higher degree than is'possible with heating stoves oi the ordinary type since the air in its course through the chamber 9.v

is heated both from the body oi the stove and the outer surrounding heating chamber 10. i In the drawings; I'Vhave shown by arrows the circulaf .tion of air and prbducts of combustion through the stove and the circulation established when the damper 311e epee. p f

Having thus described the invention, what claim `1. A stove comprising u base having a. fire box, and a body supportedupon the base und comprising inner, outer endl intermediate shells. forming a. combustion chamber and inner and outer heating chambers, the upperI end df ythe combustion chamber being in communication through noonersy passages with the upper end of the outer heating chambei', combined with a crown drum in communication'with the combustion chamberand upper end of the intermediete heating chamber, the latter being open at its lower end to the atmosphere, a damper controlling communica- `tion between the combustion chamber and crown drum, jan exhaust flue communicatingV with the upper and lower portions of the outer. heating chamber, and a damper con trolling the upper communicating passage.

'2. A stove comprising a base having a tire box, an inner drum or shell in communication at its lower'` end with =,the re box and providedA with inlets at its upper end, a

damper controlling said inlets, inner and outer heating jackets inclosing said shell and forming intervening heatchambeis, the inner heating chamber' being open at its upper and lowerends and the outer chamber closed at both ends, a crown drum or hood in communication with the upper end of the intermediate heating chamber, nues lleading from the upper end of the inner shell to the outer heating chamber, an outlet pipe haring communieatingv connections with the upper and lower ends "of the outer heating chamber, and a controlling damper in the `upper connection.
